I have a virus, McAfee not working properly

I started up my laptop and instantly got a popup prompting me to use my antivirus software. But it was a weird icon and clearly not McAfee, which is my software. I don't know where this came from so I shut down my computer. I restarted in safe mode and opened McAfee. It said it could not fix the problems because of "errors." I ran a full scan and it detected and quarantined one item (a trojan, apparently). I restarted normally, still with the same problems. Restarted in safe mode again and still McAfee won't fix the problems. Please help!

Update: I opened up the Action Center in the Control Panel. It says the Windows Security Center is turned off. I click "turn on now" and it simply tells me "The Windows Security Center service can't be started." My computer will not allow me to turn on any kind of security settings. No explanations or anything, just tells me I can't do it. I don't know what to do.

My laptop won't let me run any app out of safe mode. The fake AV software says it can't execute the program because such-and-such file is infected, and the file name changes every second as if multiple files are infected. PLEASE someone help me, the spring semester starts Monday and I need my laptop.

The reason I say AV is a waste is, if a virus is released into the wild today, it could take about a week before the AV companies add it's signature to it's updates. What good is that? How many machines get infected in that time? It's only pure luck that your machine isn't one of them.

You may want to tap f8 on bootup and then select safemode with networking. Then download and install malwarebyteshttp://www.filehippo.com/download_m...update it and run a full scan. See if that clears up your problem. If not, there are other softwares we can try

I got it also and contacted McAfee. They were no help. Restore your computer to a couple of weeks ago and download AVG (http://free.avg.com/us-en/download-avg-anti-virus-free) it blocks the pesky WIN 7, 2012 security virus. Here is McAfee told me when I complained thier antivirus didn't stop a virus:

We continually strive to keep our customers secure online by updating our virus libraries on a daily basis. However, you will agree with me that the world wide web being a dynamic medium, plenty of new variants / mutants of viruses hit the net possibly every other minute....In this scenario, even with the top of the charts antivirus softwares like McAfee, it is quite possible that at certain times, the online vulnerability increases.

So McAfee cannot protect your computer from the dynamic web! Why do they sell a product for computer protection if the web is too dynamic for them? Use AVG or Avast. Just security and protection without the pitiful excuses about their short comings.
